Title: Photometric operation apparatus
Inventor: IMAI YUJI
IPC: G03B7/08
Filed: 1987-01-29
Abstract: PURPOSE:To perform the A/D conversion of a BV (the brightness index of an object) value with high resolving power, by dividing the brightness of the object into a plurality of sections and allotting the dynamic range of an A/D converter circuit in each of the section. CONSTITUTION:The photoelectric conversion output of a light receiving element 1 is compressed by a logarithmic compression circuit 41 and the output of the circuit 41 is shifted in a level by a level shift circuit 43. The output shifted in a level is amplified by an amplifying circuit 44 and converted to digital output by an A/D converter circuit 45. The digital output after A/D conversion is inputted to an operation means 47. A zone detection means 46 detects the brightness of an object in a state divided into a plurality of sections and the output thereof is also inputted to the means 47. By this constitution, the means 46 divides the brightness range of the object into a plurality of sections and detects what sections the brightness of the object is present in. Since operation is performed on the basis of the output of the means 46 by the means 47, the dynamic range of the photometric value obtained by the means is expanded.

Title: High-speed pull-in circuit for automatic line equalizer
Inventor: MARUYAMA KAZUYOSHI
IPC: H04Q3/42
Filed: 1992-02-05
Abstract: PURPOSE:To shorten pull-in time by completing charging to a capacitor in a short time by providing a capacitor discharging voltage limit part to limit the decrease of the voltage value of the capacitor caused by discharging until reaching a prescribed value. CONSTITUTION:Received signals amplified by a variable amplifier 1 are inputted to comparators 3 and 4. When the peak is detected by the comparator 3, a capacitor 53 of a voltage conversion part 5 is charged. When the received signals are interrupted, a diode 64 of a high-speed pull-in circuit 6 is conducted, and the capacitor 53 is discharged at high speed through a resistor 65. When the voltage value of the capacitor 53 is decreased and reaches the prescribed finite voltage value, a diode 71 of a capacitor discharging voltage limit part 7 is turned to a conductive state, and a voltage corresponding to the prescribed finite voltage value is impressed from a power source to the capacitor 53. Therefore, the decrease of the voltage value of the capacitor 53 caused by discharging is limited to reach the prescribed finite voltage value corresponding to the maximum amplifying characteristic of the variable amplifier 1.

IPC: H01L21/60
Filed: 1985-02-05
Abstract: PURPOSE:To detect the electrical generation of positional displacement, and to remove a product under the state of joining having little reliability initially as a defective by forming a dummy pattern near a substrate pad to be joined with a bump for an IC chip. CONSTITUTION:One parts of the contours of dummy patterns 3a, 3b, 3c, 3d each have shapes along the contours of conductor pads 1a, 1d, 1e, 1h, and are arranged at some predetermined distances from the pads. the distances are changed according to the magnitude of the quantity of positional displacement permissible among bumps for an IC chip and substrate pads. When the bumps 5a-5h for the IC chip 4 and the substrate conductor pads 1a-1h are position- displaced at tolerance limits or more and joined, the bump such as the bump 5a is also brought into contact with the dummy pattern 3a simultaneously. Accordingly, the substrate pad 1a and the dummy pattern 3a are short-circuited electrically, thus detecting positional displacement at tolerance limits or more when the open-short-circuit of 1a and 3a is inspected electrically.

Abstract: PURPOSE:To enable realization of an ink jet head with stable characteristics as a laminated pressed body of a nozzle plate and a separate reinforcing plate by applying the reinforcing plate as a nozzle forming member on the ink discharge side of the member and fastening the reinforcing plate to the external frame of an ink jet head or holding said plate using a spring member. CONSTITUTION:Ink is supplied to an area near a nozzle 28 from an ink reserver 24 and becomes full there. If a voltage is applied between a common electrode 51 and a pattern electrode 54, a piezoelectric element contracts due to a piezoelectric effect. If the meantime, the layer of the pattern electrode 54 has a limited size change due to its high modulus of elasticity, and a bending moment occurs on the side of the common electrode 53. As a result, the free end of a vibrator 52 is deformed and displaced to the direction of a nozzle plate 27, and the ink in the nearby area is discharged from a nozzle. Simultaneously the nozzle plate receives the pressure of ink, causing a bending vibration. However, the nozzle plate is characteristically stable and free from vibration under the pressure of a reinforcing plate 34. The reinforcing plate should be installed at a height of at most, 2m/m.
